摘要 | An optical system for coupling a laser radiation source to a circularly symmetric single-mode optical fiber. The laser radiation source produces a beam of light having an elliptical mode field. The input end of a coupling fiber, which has a core that is elliptically-shaped in cross-section, is situated in light receiving relationship with respect to the source. The coupling fiber is oriented with respect to the source such that the mode field of the source is aligned with the coupling fiber core to provide the most efficient coupling of light from the source to the fiber. Means such as an evanescent coupler couples light from the output end of the fiber to the circularly symmetric fiber. |
其他摘要 | 一种用于将激光辐射源耦合到圆形对称单模光纤的光学系统。激光辐射源产生具有椭圆模场的光束。耦合光纤的输入端具有横截面为椭圆形的芯,其相对于光源处于光接收关系。耦合光纤相对于光源定向,使得光源的模场与耦合光纤芯对准,以提供从光源到光纤的最有效的光耦合。诸如渐逝耦合器的装置将来自光纤输出端的光耦合到圆形对称光纤。 |
